  2. Geospatial PDF - Wikipedia

    en.wikipedia.org/wiki/Geospatial_PDF

    Find and mark location coordinates. Measure distance, perimeter, and area. Change the coordinate system and measurement units. Copy location coordinates to the clipboard, and then use them to show locations in several web mapping services. Register a raster image to create a geospatially aware PDF.

  3. Geographic coordinate conversion - Wikipedia

    en.wikipedia.org/wiki/Geographic_coordinate...

    Coordinate conversion is composed of a number of different types of conversion: format change of geographic coordinates, conversion of coordinate systems, or transformation to different geodetic datums. Geographic coordinate conversion has applications in cartography, surveying, navigation and geographic information systems.

  4. ArcGIS - Wikipedia

    en.wikipedia.org/wiki/ArcGIS

    ArcGIS is a family of client, server and online geographic information system (GIS) software developed and maintained by Esri. ArcGIS was first released in 1982 as ARC/INFO, a command line-based GIS. ARC/INFO was later merged into ArcGIS Desktop, which was eventually superseded by ArcGIS Pro in 2015. [8]

  5. Geographic information system - Wikipedia

    en.wikipedia.org/wiki/Geographic_Information_System

    Geographic information system (GIS) is a commonly used tool for environmental management, modelling and planning. As simply defined by Michael Goodchild, GIS is as "a computer system for handling geographic information in a digital form". [66] In recent years it has played an integral role in participatory, collaborative and open data philosophies.

  6. Data model (GIS) - Wikipedia

    en.wikipedia.org/wiki/Data_model_(GIS)

    The Mahomet Sand is continuous in this area, and represents one occurrence of this unit in the data model. Each raster, or pixel, on the Mahomet Sand surface has a set of map coordinates that are recorded in a GIS (in the data model bin that is labeled "pixel coordinates", which is the raster corollary of the "geometry" bin for vector map data).

  7. WKT can describe coordinate reference systems. For example, the WKT below describes a two-dimensional geographic coordinate reference system with a latitude axis first, then a longitude axis. The coordinate system is related to Earth by the WGS84 geodetic datum:

  8. Universal Transverse Mercator coordinate system - Wikipedia

    en.wikipedia.org/wiki/Universal_Transverse...

    The Universal Transverse Mercator (UTM) is a map projection system for assigning coordinates to locations on the surface of the Earth.Like the traditional method of latitude and longitude, it is a horizontal position representation, which means it ignores altitude and treats the earth surface as a perfect ellipsoid.

  9. Georeferencing - Wikipedia

    en.wikipedia.org/wiki/Georeferencing

    Graphical view of the affine transformation. The registration of an image to a geographic space is essentially the transformation from an input coordinate system (the inherent coordinates of pixels in the images based on row and column number) to an output coordinate system, a spatial reference system of the user's choice, such as the geographic coordinate system or a particular Universal ...
